Energy: Forms, Transformation, Transfer, and Conservation
Motion energy (kinetic energy) is associated with the speed and the mass of an object.
Item EG009003: For two objects that are traveling at the same speed, the object with more motion energy weighs more.
Object 1 and Object 2 are traveling at the same speed, but the motion energy (kinetic energy) of Object 1 is greater than the motion energy of Object 2. Does Object 1 weigh more than, less than, or the same as Object 2?
- Object 1 weighs more than Object 2.
- Object 1 weighs less than Object 2.
- Object 1 weighs the same as Object 2.
- More information is needed to compare the weights of the objects.
